  • Objective To derive further studies evaluating the effectiveness of Cultured Wild Ginseng Pharmacopuncture (CWGP) Therapy on squamous cell carcinoma as a first line. Methods Three cycles (4 weeks/cycle) of CWGP were administered as a dosage of 10 ml per day. Patient was diagnosed with stage IIIB squamous cell carcinoma and refused all therapy of conventional medicine because of old age and cardiac invasion of tumor. Intensive treatment of CWGP for 3 cycles was done on the patient. Computed Topography (CT) was performed to evaluate the therapeutic efficacy. Results After the intravenous infusion of 2 cycles of CWGP, chest CT revealed the mass size and pleural invasion sustained stable disease. After the point injection of 1 cycle of CWGP, chest CT revealed progressive disease. The disease free survival rate was 1 month. Conclusion This case may provide us the possibility that CWGP offers potential benefits for patients with squamous cell lung carcinoma. But this is a single case study and further case-series research should be compensated.

  • Objectives: The purpose of this study was to examine the single-dose intravenous toxicity of Guseonwangdo-go glucose 5% pharmacopuncture (GWG5). Methods: Forty Sprague-Dawley rats were divided into four groups of five males and five females per group: an intravenous (IV) injection of 1.0 mL of normal saline solution per animal was administered to the control group; IV injections of 0.1, 0.5, and 1.0 mL of GWG5 per animal were administered to the experimental groups (G: 0.1, G: 0.5, and G: 1.0). Observation of clinical signs and body weight measurements were carried out for 14 days following the injections. At the end of the observation period, hematological, biochemical, and histopathological tests, as well as necropsy examinations, were performed on the injected parts. Results: No mortalities or adverse clinical signs were observed in any of the groups. The body weights of all groups continuously increased. In the hematological and the biochemical tests, females in G-0.1 had minimal changes, but those changes were not dose dependent. On necropsy examination, no abnormalities were observed. In the histopathological test, focal inflammatory cell infiltrations were observed in two female rats, one in the control group and one in G-1.0. Also, one female rat in the control group had an epidermis crust. These changes were concluded to have been caused by the insertion of the needle into a vein. Conclusion: The above findings suggest that the lethal dose of GWG5 administered via IV injection is more than 1.0 mL per animal in both male and female rats. Further studies are needed to establish more detailed evidence of its toxicity.

  • The effects of isoproterenol, a sympathomimetic amine, on the mast cells in the oral mucosa were cytochemically studied in twenty four healthy male albino rats weighing approximately 100gm. seven groups of three each were injected intraperitoneally, as a single dose of 8mg/100gm. body wt., (dissolved in 0.9% saline 0.2㎖). Each groups were sacrificed following ether anesthesia at he time indicated, 1. 2. 3. 5. 7. 10. 14days after only a single injection. One normal group is not administered with any substances. The sections of oral mucosa were stained with 0.005% toluidine blue (Mowry's method) and alcian blue (pH 2.5). We found that isoproterenol made an initial decrease in the metachromasia and alcian blue affinity, and the number of mast cell, followed by an subsequent return to normal.

  • The interface between nanomaterials and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics and many areas of engineering, biomedicine. The combination of these diverse areas of research promised to yield revolutionary advances in healthcare, medicine, and life science. For example, the creation of new and powerful nanosensors that enable direct, sensitive, and rapid analysis of biological and chemical species can advance the diagnosis and treatment of disease, discovery and screening of new drug molecules. Nanowire based sensors are emerging as a powerful and general platform for ultrasensitive and multiplex detection of biological and chemical species. Here, we present the studies about noble metal nanowire sensors that can be used for sensitive detection of a wide-range of biological and chemical species including nucleic acids, proteins, and toxic metal ions. Moreover, the optical and electrochemical applications of noble metal nanowires are introduced. Noble metal nanowires are successfully used as plasmonic antennas and nanoelectrodes, thereby provide a pathway for a single molecule sensor, in vivo neural recording, and molecular injection and detection in a single living cell.

  • A study detennined whether certain biochemical and physiological variables were altered during marginal Zn deficiency. Ten weaned crossbred Hereford Angus heifer calves, weighing $163{\pm}2kg$, were utilized. Five calves were fed a Zn - deficient (- Zn) brome-alfalfa hay diet containing 17 mg Zn/kg diet DM, and five calves were fed a Zn-adequate (+Zn) diet with 23 mg Zn/kg diet DM from $ZnSO_4$ added to the - Zn diet (total diet, 40 mg Zn/kg diet DM), for 32 d. At 21 d the - Zn calves had a reduction (p < .05) in feed efficiency. By 25 d, plasma Zn and alkaline phosphatase concentrations were reduced (p < .05) in the - Zn calves. Blood urea nitrogen, glucose, insulin, IGF-I, Cu plasma concentration and Zn and Cu concentrations of red blood cell (RBC) and liver were not altered (p > .05) by the - Zn diet through 25 d. In response to a single i. m. injection of dexamethasone (20 mg) on d 25, calves fed the two dietary Zn amounts showed no changes (p > .05) in plasma or RBC Zn and Cu concentrations, serum IGF-I, insulin, and glucose when measured at 6, 12, 24, 48, 72, and 96 h after injection. In response to an intradermal injection of phytohemagglutinin on d 30, cell mediated immune (CMI) response was reduced (p < .05) in the - Zn calves. These observations indicate that during a marginal Zn deficiency in calves, there was a decrease in feed efficiency, plasma Zn, serum alkaline phosphatase, and CMI response.

  • This experiment was carried out to investigate the influence of Aloe vera in the pancreatic islets of streptozotocin diabetic mice. Experimental diabetes was induced in ICR mice with a single injection of SZ(140mg/kg body weight, ip). The mice demonstrating hyperglycemia 48 hours after SZ injection were treated for 16 days with Aloe vera(300, 800mg/kg). Plasma glucose was measured, and for morphological studies of the islets specimens were stained with hematoxylin-eosin and by immunocytochemical methods. Then we observed the morphological changes of islets. Polymorphonuclear cells were infiltrated at the periphery of the islets 48 hours after SZ injection in SZ-treated ICR mice, but no prominent WBC infiltration was observed throughout the experiment. Blood glucose in mice treated with Aloe vera after SZ injection was higher than that of SZ injected mice, and mononuclear cells were heavily infiltrated at the islets 16 days after Aloe vera treatment(300mg/kg), and significant islets infiltration of mononuclear cells was observed 30 days after Aloe vera treatment(800mg/kg). Islets of ICR mice treated with Aloe vera after SZ injection showed severer insulitis, degranulation and necrosis of B cells than those of SZ injected mice. These studies indicate that Aloe vera in SZ injected mice increases vascular permeability and number of WBC in pancreatic islets, and potentiates destruction of B cells by cell-mediated immune system.

  • Objectives : The aim of the present study was to observe the effect of Astragali Radix Herbal-Acupuncture Solution(AR-HAS) at $ST_{36}$(jok-samni, $Z\acute{u}s\bar{a}n$ Li) on collagen- II -induced arthritis(CIA) in mice. Methods : DBA/1J mice were immunized with bovine type II collagen(CII) on days 0 and 21 to induce arthritis. The mice were divided into 5 groups : normal group(no CIA), control group(CIA+no treatment), needle prick group(CIA+single prick with an injection needle), saline group(CIA+saline injection) and ARHA group(CIA+ R-HA treatment). The needle prick, saline injection, and AR-HA groups were injected on the right $ST_{36}$(jok-samni) of mice for 9 weeks, 3 times a week, beginning 4 weeks after the booster immunization. Results : 1. The incidence of arthritis, AI(arthritis index), and joint edema decreased in the AR-HA group. 2. Weight gain, hypertrophy of the spleen, adhesion of the tissues, and transformation of the joint were restrained in the AR-HA group. 3. The concentrations of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, $IFN-{\gamma}$ in CIA mouse serum and $IFN-{\gamma}$, IL-10 in the CIA mouse spleen cell culture decreased significantly at $ST_{36}$ in the AR-HA group. 4. Total cell counts increased significantly, and the ratio of $CD3e^+$ to $CD45R^+$, $CD4^+$ to $CD8^+$, and $CD4^+$ to $CD25^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse spleen cell culture of the AR-HA group. 5. Total cell counts decreased significantly, and $CD4^+/CD25^+$ and $CD45R^+/CD69^+$ decreased significantly at $ST_{36}$ in the CIA mouse lymph nodes of the AR-HA group. 6. $CD3e^+/CD69^+$ and $CD11b^+/Gr-1^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse joints of the AR-HA group. 7. The histological examination showed that cartilage destruction and synoviocyte proliferation decreased in the CIA mouse joints of the AR-HA group, and collagen fiber was expressed similar to that seen in the normal group. Conclusions : Our experiments show that at $ST_{36}$, an anti-inflammatory mechanism of AR-HA controls synovial cell proliferation and protects against cartilage destruction in rheumatoid arthritis.

  • Background and Objectives: Numerous studies were conducted to develop radiosensitizers to increase antitumor effect and decrease systemic toxicity of ionizing radiation. In current study, the authors tested the synergistic effect of mutant $TNF-{\alpha}(M_3S)$ with radiation therapy on heterotransplanted hypoparyngeal squamous cell carcinoma. Materials and Method: SNU-1041 cell line was heterotransplanted to nude mice. When the tumors grew up to $70mm^3$ or more, the animals were randomly placed into 4 groups(n=10/group). Group I : 0.1ml of normal saline injected intraperitoneally once a day for 5 days. Group II : 10ug of $TNF-{\alpha}$ injected intraperitoneally once a day for 5 days. Group III : a single radiation dose of 10 Gy per animal delivered. Group IV : single radiation dose of 10 Gy was delivered 1 hour after intraperitoneal injection of $TNF-{\alpha}$ 10 ug. Results: Four weeks after treatment, group IV showed the least tumor growth during the 4 weeks follow up and the relative tumor growth rate(RTG) of each groups after 4 weeks were 31, 5.8, 10, and 3.2 respectively(p<0.05). Conclusion: These study suggests that pretreatment with $TNF-{\alpha}$ can significantly enhance the effects of radiation therapy and further studies may be needed for clinical trials of combination treatment of $TNF-{\alpha}$ and radiation.

  • To precisely analyze the role of ovarian steroids in the regulation of laminin chain gene expression in mouse uterine tissues, the ovariectomized mouse model was used. Ovariectomized mice received a single injection of steroid hormones and total RNA was isolated from whole uterine tissues. Messenger RNA levels of each laminin chain (A, 81, and 82) were determined by competitive RT-peR procedures. Estradiol decreased mRNA levels of laminin 81 chain about two-fold, and 82 chain rather moderately. Estradiol-induced inhibition of laminin 81 and 82 chain mRNA levels were completely blocked by pretreatment with estrogen receptor antagonist tamoxifen. Estriol, a short acting estrogen which cannot induce hyperplastic responses of rodent uterine tissues, also showed an inhibitory effect on 81 and 82 chain mRNA levels, while estrone, an inactive estrogen, failed to influence either 8 chain mRNA levels. Effects of steroids on A chain mRNA level were quite different from those on 8 chains. Laminin A chain mRNA level was slightly increased by estradiol treatment, but negatively affected by progesterone. Progesterone treatment greatly increased both 8 chain mRNA levels, but slightly decreased A chain mRNA level compared to the control. The effect of progesterone on laminin chain-specific mRNA levels was further increased by co-injection of estradiol in a time-dependent manner. Progesterone-induced 81 and 82 chain mRNA transcription was inhibited by RU486, a synthetic anti-progesterone /anti-glucocorticoid. The present study demonstrates for the first time that steroids are able to regulate laminin gene expression in mouse uterine tissues, indicating that steroid-regulated laminin gene expression is involved in uterine growth and probably differentiation.

  • Systemic lupus erythematosus (SLE) is a systemic inflammatory autoimmune disease characterized by abnormalities in T cell immunoregulation and hyperreactivity of B cells, leading to autoantibody production and multiorgan injuries. We investigated the effect of baicalin on aberrant immunoregulation in pristane-induced lupus mice. Mice received i.p. a single injection of 0.5 ml of pristane or PBS, and approximately 3 months later, were used as a pristane-induced lupus model or healthy controls. The pristane-induced lupus mice and healthy mice were randomly divided into three groups: healthy mouse group (healthy control), pristane-primed lupus control group (lupus control), and baicalin (BAC)-treated pristane-primed lupus mouse group (BAC-treated lupus). The pristane-induced lupus mice and healthy mice were administrated orally with BAC 50 mg/kg or PBS once in a day for 10 ds. These results demonstrated that levels of serum IL-6, LPS-induced production of IL-6, $PGE_2$ and NO by macrophages, $PGE_2$-stimulated production of IL-6 by macrophages and IFN-${\gamma}$ by thymocytes, and an overexpression of splenic NKT cells and CD69+CD4+ T cells were downregulated in BAC-treated lupus compared to lupus control, while reduced apoptosis of splenic CD4+ T cells were upregulated. Therefore, these findings suggest that BAC may attenuate autoimmunity and disease activity in lupus via downregulation of aberrant activation of T cells and inhibition of overproduction of IL-6 and $PGE_2$ in pristane-induced lupus mice.
